Bsc, line-level or @ speaker terminals?

No filter will take into account the complexities of the baffle diffraction... unless it is applied to a very well behaved shape you will have ripple. (sphere or "teardrop")

The pot allows you to dial in the amount of cut for your room.

The F3 he uses is the standard value used for F3, a number literaly pulled from drawing a few lines on the charts from Olson research. This number is always a ballpark, and will need to be adjusted based on cabinet shape.

Thank you for that Dave

My initial calculations showed 500 something Hz as a good f3 point.
After doing the simulations I found out that approximatly (almost) -6dB at that frequency was a much better choice for my speakers.
So yes... I'd say there's room for some adjustments.
